RELATED APPLICATIONS

The present application claims priority to EP Patent Application No. 20200976.7, filed Oct. 9, 2020, the contents of which are hereby incorporated by reference in their entirety.

BACKGROUND INFORMATION

Hearing devices are generally small and complex devices. Hearing devices can include a processor, microphone, speaker, memory, housing, and other electronical and mechanical components. Some example hearing devices are Behind-The-Ear (BTE), Receiver-In-Canal (RIC), In-The-Ear (ITE), Completely-In-Canal (CIC), and Invisible-In-The-Canal (IIC) devices. A user can prefer one of these hearing devices compared to another device based on hearing loss, aesthetic preferences, lifestyle needs, and budget.

When a hearing device is bought, usually a hearing care specialist or fitter fits the hearing device by adjusting hearing programs and parameters of these hearing programs to the needs and/or the hearing loss of the user. For example, when the user is interested in hiking and has problems with wind noises, the user may go to the office of the fitter, who may adjust the hearing device with respect to the suppressing wind noises. It may be that the fitter plays sound examples in his office, where the user can test the new settings. After that, the user has to test the new setting in the field, i.e. in the same situation, where he had problems. If he still has problems, he has to return to the fitter's office and the fitting procedure has to be repeated again.

This procedure may be cumbersome and time-consuming.

WO 2015/192 870 A1 describes a method for evaluating an individual hearing benefit, where the user can switch on and off an effect of an advanced hearing device feature, which was automatically selected based on classification of a current hearing situation.

DETAILED DESCRIPTION

Described herein are a method, a computer program and a computer-readable medium for adjusting and fitting a hearing device. Furthermore, the embodiments described herein relate to a hearing and fitting system with a hearing device and optionally a mobile device.

Described herein is a feature to test, whether a setting of a hearing device made at the fitter's office is usable during the everyday life of the user of the hearing device. A further feature described herein is to improve and simplify the fitting of a hearing device.

These features are achieved by the subject-matter of the independent claims. Further exemplary embodiments are evident from the dependent claims and the following description.

A first aspect relates to a method for adjusting a hearing device. The hearing device may be part of a hearing system, which additionally may comprise a mobile device, such as a Smartphone, Smartwatch, tablet computer, etc. The hearing device may be worn by a user, for example behind the ear or in the ear. The hearing device may be a hearing aid for compensating a hearing loss of a user. Here and in the following, when to a hearing device is referred, also a pair of hearing devices, i.e. a hearing device for each ear of the user, may be meant. A hearing device may comprise one or two hearing aids and/or a cochlear implant.

According to an embodiment, the method comprises: generating an audio stream with a microphone of the hearing device and processing the audio stream with a sound processor of the hearing device thus providing a processed audio stream and outputting the processed audio stream to a user of the hearing device. The audio stream may be generated in the hearing device by digitizing a sound signal with a microphone of the hearing device. The sound processor may be controlled via sound processing parameters, which define, how the audio stream is processed, for example which frequencies are amplified and which are attenuated, which frequencies are shifted and/or whether frequency bands are compressed. The sound processing parameters also may define, how and which kind of noise is suppressed and/or whether sound from specific directions are amplified or not (which may be called beam forming). These sound processing parameters may be stored in the hearing device.

According to an embodiment, the method comprises: detecting a hearing situation with a hearing situation detector, wherein the hearing situation is associated with a configurable sound processing parameter adjustable by the user of the hearing device. The hearing situation may be determined by analyzing sensor data acquired by one or more sensors of the hearing system comprising the hearing device. For example, the hearing system may further comprise a mobile device carried by the user providing a sensor, which data is analyzed. The sensor data may comprise the audio stream, GPS data, audio data acquired by the mobile device, etc. This data may be evaluated by the hearing situation detector, which may be a program in the hearing device and/or the mobile device. The hearing situation detector may output hearing situation classification v, which are derived from the data. Examples for hearing situations, which may be classified in such a way are speech, noise, music, speech in noise, wind noise, car noise, restaurant noise, etc. For each such situation, a hearing situation classification value may be output, such as 0 and 1 or a percentage value for the probability of such a hearing situation.

The association of the hearing situation with the configurable sound processing parameter may be done by a fitter in the fitting office. With a fitting computer in data communication with the hearing device and/or the hearing system, the association may be set in the hearing device and/or the hearing system.

According to an embodiment, the method further comprises: when the hearing situation is detected, providing a user interface to the user of the hearing device for adjusting the configurable sound processing parameter, and when the user has adjusted the configurable sound processing parameter, applying the configurable sound processing parameter to the sound processor. When a hearing situation is detected with an associated configurable sound processing parameter, the user may be informed about this with the aid of a user interface. For example, this may be done with an acoustical and/or graphical user interface of the hearing system. Furthermore, the user is provided with a possibility to adjust the configurable sound processing parameter with the user interface. A user interface element may be provided to the user, where he or she can select specific values for the configurable sound processing parameter. The possible values may have been chosen by a fitter of the hearing device, for example in a fitter's office. After the selection by the user, the adjusted configurable sound processing parameter is applied to the sound processor and the user directly can decide, whether the adjusted sound parameter is better or inferior to the previous situation. In such a way, the user can test several proposals of the fitter for hearing device settings directly in the real hearing situation.

It also may be that the user is asked via the user interface, whether the real hearing situation has been identified correctly. If this is not the case, also information, such as the audio stream and/or the hearing situation may be stored, for example to be later analyzed. This may help the fitter to better define hearing situation definition data, when the user returns to his office.

These and other aspects will be apparent from and elucidated with reference to the embodiments described hereinafter.

FIG. 1 schematically shows a hearing system 10 with a hearing device 12 in the form of a behind-the-ear device and a mobile device 14. It has to be noted that the hearing device 12 is a specific embodiment and that the method described herein also may be performed by other types of hearing devices, such as in-the-ear devices.

The hearing device 12 comprises a part 15 behind the ear and a part 16 to be put in the ear channel of a user. The part 15 and the part 16 are connected by a tube 18. In the part 15, a microphone 20, a sound processor 22 and a sound output device 24, such as a loudspeaker, are provided. The microphone 20 acquires environmental sound and generate a sound signal, which is converted into an audio stream. The sound processor 22 amplifies the audio stream and the sound output device 24 generates sound that is guided through the tube 18 and the in-the-ear part 16 into the ear channel of the user.

The hearing device 12 may comprise a processor 26, which is adapted for adjusting sound processing parameters of the sound processor 22. For example, with the sound processing parameters, an output volume of the audio stream may be frequency dependent adjusted. These sound processing parameters are determined by a computer program run in the processor 26, which will be described below in more detail. In particular in specific hearing situations, a configurable hearing program with specific sound processing parameters may be started and the user may configure specific parameters of the hearing device and/or of the configurable hearing program with a user interface.

For example, the user interface may be an acoustical user interface, which is provided by specific sounds generated by the hearing device 12. With a knob 28 of the hearing device 12, the user may generate commands to configure the configurable sound processing parameter.

All these functions may be implemented as computer programs stored in a memory 30 of the hearing device 12 and/or the mobile device 14, which computer programs may be executed by the processor 22.

The hearing device 12 also may comprise a sender/receiver 32 for data communication with the mobile device 14, which may be a smartphone or tablet computer. The user interface mentioned above also may be provided by the mobile device 14 as graphical user interface 34. An indicator element 36 may indicate the currently selected configurable hearing program and the user may select different parameter sets of the configurable hearing program with a selector element 38 and/or may adjust specific parameters with graphical elements, such as slider elements 40.

It also may be that the hearing device 12 and/or the mobile device 14 comprises a sensor 33, such as an acceleration sensor, a temperature sensor, a humidity sensor, a GPS sensor, etc.

FIG. 1 furthermore shows a fitting device 42, such as a PC, which may be situated in a fitter's office. The fitting device 42 is adapted for starting data communication with the hearing device 12 and optionally with the mobile device 14. Configurable hearing programs may be generated with the fitting device 42 and stored in the hearing device 12. The fitting device 42 may read out adjustments and selections made by the user with the user interface 34. Corresponding parameters of the configurable hearing program also may be read out of the hearing device 12 and optionally the mobile device 14.

The fitting device 42 together with the hearing system 10 may be seen as a fitting system 43.

FIG. 2 shows a functional diagram of the hearing system 10. Also a method for adjusting the hearing device 12 will be illustrated with respect to FIG. 2 .

The microphone 20 of the hearing device 12 generates an audio stream 44, which may be supplied to a hearing situation detector 46. If the hearing device 12 and/or the mobile device 14 has a further sensor 33, the sensor signal 45 additionally or alternatively may be supplied to the hearing situation detector 46. The hearing situation detector 46 analyzes the audio stream 44 and/or the sensor signal 45 and determines hearing situation classification values 50. The hearing situation detector 46 may be implemented as software module in the hearing device 12 and/or the mobile device 14 and/or may be executed by a processor 26.

The hearing situation classification values 50 may be indicative of a specific hearing situation in the environment of the user. For example, the hearing situation classification values 50 may be probability values for specific features, which can be extracted from the audio stream, such as wind noises, car noises, music, etc.

One or more of the hearing situation classification values 50 may be determined with a sound classifier 48, i.e. a computer program adapted for identifying a specific hearing situation. The hearing situation detector 46 may comprise a plurality of sound classifiers 48. Each sound classifier 48 may output at least one sound classification value 50 with respect to a specific hearing situation. It also may be that at least one of the sound classifiers 48 is based on a machine learning algorithm. For example, such a classifier 48 may be based on a neuronal network and/or may have been trained with classified audio streams.

The sound classification values 50 are input into a program selector 52, which, when specific criteria are met for a hearing situation, starts a corresponding hearing program. The program selector 52 may be implemented as software module in the hearing device 12 and/or may be executed by the processor 26.

A hearing program 58, 60 is started by applying sound processing parameters 54 to the sound processor 22. The sound processor 22 processes the audio stream 44 with the actual applied sound processing parameters 54. For example, the sound processor 22 is adapted for at least one of frequency dependent amplifying the audio stream 44, frequency shifting the audio stream 44 and frequency compressing the audio stream 44 in dependency of the applied sound processing parameters 54. The amplification and/or frequency shifting may be encoded with the sound processing parameters 54.

The processed audio stream 56 is output with the sound output device 24, such as a loudspeaker, to the user.

The hearing programs 58, 60 are stored in the memory 30 of the hearing device 12. Each hearing program 58, 60 may comprise a data structure encoding, in which hearing situation the hearing program 58 is started and which sound processing parameters 54 are applied to the sound processor 22 in this case. In general, the hearing device 12 comprises a plurality of preset hearing programs 58 and at least one configurable hearing program 60.

A hearing program 58, 60 may started, when a specific set of hearing situation classification values 50 is determined by the hearing situation detector 46.

Each hearing program 58, 60 may comprise hearing situation definition data 62 defining ranges for hearing situation classification values 50. When the hearing situation classification values 50 are within these ranges, it is assumed that the hearing situation is met and the corresponding hearing program is started.

Furthermore, each hearing program 58, 60 comprises sound processing parameters 64, which are applied to the sound processor 22, when the hearing program 58, 60 is started.

The preset hearing programs 58 and the configurable hearing program 60 are different in that the configurable hearing program 60 also defines possibilities, how the user is able to adjust sound processing parameters 64. The configurable hearing program 60 may comprise adjustment data 66, which defines at least one configurable sound processing parameter. At least, the configurable hearing program 60 comprises at least one association with a configurable sound processing parameter. For example, the configurable hearing program 60 may comprise at least two sets of sound processing parameters 64, 68 as adjustment data 66, each of which is selectable by the user. It also may be that the adjustment data 66 defines a set of selectable values for an adjustable sound processing parameter 70.

When the configurable hearing program 60 is started, this information is sent to a user interface module 72. The user interface module 72, which may be a software module executed in the mobile device 14, may inform the user about the starting of the configurable hearing program 60. For example, a name of the configurable hearing program 60 may be displayed with the indicator element 36.

Furthermore, information on the possible adjustments may be sent to the user interface module 72, for example, that the user can select different sets of sound processing parameters 64, 68 and/or that different values are selectable for an adjustable sound processing parameter 70. This information may be encoded in the adjustment data 66 and/or may be provided to the user with a selector element 38 and/or one or more slider elements 40.

When the user has selected and/or adjusted one or more configurable sound processing parameters with the user interface 34, this information is sent back to the program selector 52. The program selector 52 then applies the adjusted sound processing parameters 54 to the sound processor 22. The hearing device 12 processes the audio stream 44 in a different way and the user can directly hear the difference.

The above described adjustment method may be used for providing newly configured hearing programs to a user, such that the user can test these hearing programs directly in corresponding hearing situations.

This will be described in more detail with respect to FIG. 3 , which show a flow diagram for a method for fitting a hearing device 12. This method may be performed by the fitting system as shown in FIG. 1 , i.e. the hearing device 12, the mobile device 13 and the fitting device 42.

In step S10, the user enters the office of a hearing care specialist (or fitter), either for buying a new hearing device 12 or because he is not content with the functionality of the hearing device 12. The user is asked by the fitter, in which hearing situation adaptions should be made.

In step S12, the fitter generates a configurable hearing program 60 for the hearing device 12 of the user. This is done with the fitting device 42, which may read out the configuration of the hearing device 12. For example, a configurable hearing program 60 may be made by adjusting a preset hearing program 58 with the fitting device 42. Such adjusting may not be possible to be performed with the hearing system 10 alone. Furthermore, the fitter usually has much more experience in adjusting sound processing parameters 64 and in defining hearing situation definition data as the user.

In the configurable hearing program 60, also the adjustment data 66 is defined with the fitting device 42. For example, the fitter can generate more than one set of the sound processing parameters 64, 68 and/or may define, which sound processing parameters can be adjusted by the user and in which extent.

In step S14, the configurable hearing program 60 is stored in the memory 30 of the hearing device 12 by the fitting device 42. It also may be that the fitting device 42 installs a computer program in the mobile device 14, which is adapted to communicate with the hearing device 12 and to provide the user interface 34. The configurable hearing program 60 also may be stored in the mobile device 14.

The user is then asked to leave the fitter's office and to go in the specific hearing situation, where the configurable hearing program 60 can be tested.

In step S16, the user enters such a hearing situation and the hearing system 10 identifies the hearing situation of the configurable hearing program 60 as described above.

In step S18, the configurable hearing program 60 is started and/or the user may select to the configurable hearing program 60. The user may be informed about this with the user interface 34.

In step S20, the user adjusts the configurable hearing program 60, for example, by selecting one of different sets of sound processing parameters or by adjusting a configurable sound processing parameter. The user can compare the different proposed settings directly in the real hearing situation and choose a setting of sound processing parameters 54, which is optimal according to his opinion.

It also may be that the hearing situation classification values 50, which have been determined at the time, when the configurable hearing program has been selected by the user and/or has been started, are stored in the configurable hearing program 60, for example in the hearing situation definition data 62. The sound definition data 62 of the configurable hearing program 60 also may be adjusted to the hearing situation classification values 50, which have been determined at the time, when the configurable hearing program 60 has been selected by the user and/or has been started.

In step S22, the user returns to the fitter's office.

In step S24, the configurable hearing program 60 and optionally the adjustments of the user are read out of the hearing system 10 with the fitting device 42. It also is possible that the user tells the fitter, which settings are the most preferred one for him. These settings are selected by the fitter in the fitting device 42.

In step S26, the fitter defines a preset hearing program 58 with the fitting device 42, wherein the preset hearing program 58 may comprise the hearing situation classification values 50 of the configurable hearing program 60 and a set of adjusted sound processing parameters 64 adjusted by the user. The fitter may further adjust the preset hearing program 58 with the fitting device 42.

In step S28, the preset hearing program 58 is stored in the memory of the hearing device 12 and/or the mobile device 10. This preset hearing program 58 may be much better adjusted to the needs of the user as other preset hearing programs 58, which solely may have been designed for a class of users and/or which are not individually adjusted.
